My post on the likelihood of Google eyeing an online/offline model generated a heap of correspondence and really got my thinking. This has to be the way of the future!

Let me point you to a company called Sharpcast. I’ve written before that I’ve been frustrated that Picasa doesn’t have both online and offline capabilities so as I can manage my photos either on my desktop or on the web. Well Sharpcast Photos does exactly that plus extends the model to mobile.

So you have three clients. One that runs on your desktop, a web client and a mobile client., all of which stay in synch, enabling you to access your photos absolutely anywhere but also in the client that delivers the best performance.

Rich, Integrated Applications — a familiar look and feel wherever you are

Speedy Recovery — recreate your collection just as you left it

The company just raised $13.5 million in Series B funding from Sigma Partners. A lot of money for a photo sharing app? No, photos is just the first service that the Sharpcast technology will drive.

Sharpcast is developing a suite of consumer services that dramatically simplifies the way people manage, access, back up and share digital media and information. With Sharpcast services, a person’s PC and mobile phone work together automatically to keep all of their media and information in sync, backed up on the web and instantly accessible wherever they are. The company’s first service, Sharpcast photos, will launch in beta later this spring.

The Sharpcast folk have promised me a look at what they’ve got to date so more on that when I get the opportunity but this is one VC funding exercise I’m not going to spurn.

Whoever solves the online/offline puzzle is sitting on a bonanza because this stuff is tough. Anyone who has ever used anything with online/offline capabilities such as Lotus Notes, knows the potential for things like replication conflicts and so forth.

This is where you so-called ‘Web 2.0′ starts to get serious. I remember way back when I was a cub reporter on Computerworld, George Colony was predicting the death of the web. He claimed desktop apps would interact with the Internet to collect information and update with central data stores, but that the client would be feature and graphic rich traditional applications.

What that ignores is that a web client is fabulous for getting access to your data regardless of where you are. It’s a teriffic lowest common denominator. But we’re a long, long way off being able to do everything in a browser that we can achieve on the desktop. Multiple clients accessing synchronised multiple sets and subsets of data, depending on use and practicality is where this industry is heading. And fast.

But when oh when is Picassa going to have an online equivalent. As much as I love Flickr, I struggle to keep it up-to-date because it’s another step in my photo filing process, which I already consider laborious.

What I want is to download my files into Picassa (preferably with some intelligent tagging) and then have the software automatically start uploading the files into the online version. ideally, online/offline should then stay synched.

That’s something I’d definitely pay for so it represents a way for Google to actually monetise its Picassa investment, as well. Quite frankly, I’m staggered this hasn’t happened already.
